In my simplistic view, the pedal will only draw as much current as it needs, and i suppose you have to go with the quoted figures. If they do not get the draw they require,they will not work as effectively, although they should still work. One thing to NOT get wrong is Voltage, too much and it fries it and its good night pedal.
Example - my 2 notes LeBass is 500mA, so i need to combine 2 ports on my power supply to drive it, when it was on one port for a small period, it worked, but no way near as good.
Its one of those things about pedals, a lot of people are happy to buy them, but seem to not want to shell out an extra hundred quid on a decent power supply (not being judgemental here!).
You may always get away with daisy chain, etc. BUT if you get a good power brick for your needs, you will never need to make do, you will have a happy long term board.
Depending on board size, where you mount it etc. I have had a decibel Eleven Hotstone Deluxe - fantastic, and anything from the Cioks family has been good to me, currently a DC5
